java - java.sql.SQLException：GET 请求时 getLong() 的值无效
问题描述
下午好，
我有一段时间遇到一个问题，我已经尝试了很多来找到解决方案，但我做不到。
首先，我的问题来自java.sql.SQLException: Invalid value for getLong(). 但是，就像我说的那样，我无法解决它，因为每个 aswers 都告诉我们试图获取一个类型为VARCHAR数据库的变量，就像一个Long类型变量一样。但是，查看我所做的模型类的范围，所有变量都是类型良好的。
我在 Spring Boot Restfull 应用程序中工作，因此，我编写了模型、存储库和资源类。
我使用 Postman 进行测试，当我向GET特定资源类发送请求时，我收到了该异常，尽管我使用相同的逻辑对其他资源进行编码，这很有效。
我的尝试之一是将插入数据库的值从字母数字字符串（如“Pessoa 1 Reu”）更改为数字字符串（如“1”），GET请求成功。
这个问题发生在一个关系类中，它关联了一个关系类和一个实体类，尽管GET每个请求都分别成功。
GET资源类方法使用我所做的存储库类的实例，就像其他人一样，它调用该方法findAll()。
如果有人可以帮助我，我会感到很感激......
---编辑---我在这篇文章的末尾
添加了's 代码。在表中，CREATE TABLE使GET请求起作用的变量是在数据库和应用程序中键入的。当该变量存储字母数字字符串时，请求将失败......cpf_cnpj_pessoapessoa_fjVARCHARStringGET
关系类：

@Table(name = "reus_advogados")
@IdClass(Reu_AdvogadoIdClass.class)
public class Reu_Advogado {

解决方案
@Column(name="num_processo_reu")
protected Long num_processo_reu;
我的尝试之一是将插入数据库的值从字母数字字符串（如“Pessoa 1 Reu”）更改为数字字符串（如“1”），并且 GET 请求成功。
查看数据库模式。此列num_processo_reu定义为VARCHAR而非数字。当值是数字的字符串表示形式时，数据库会为您进行转换。当您尝试读取非数字值时，Pessoa 1 Reu您会遇到异常，因为数据库无法将该值转换为数字。
更改数据库架构（即CREATE TABLE），使该列是数字且不能包含字符串值，或者将您的代码更改为
@Column(name="num_processo_reu")
protected String num_processo_reu;
并根据项目要求编写逻辑来处理非数字值。
